How to Fix CVE-2023-23626

To remediate this vulnerability, upgrade all affected Github.com/ipfs/go bitfield dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/ipfs/go-bitfield fixed: 1.1.0 
Upgrade github.com/ipfs/go-bitfield to 1.1.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/ipfs/go-bitfield

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-23626, inspect your project dependencies for Github.com/ipfs/go bitfield:

inspect dependencies for github.com/ipfs/go-bitfield

Analyze the terminal output to locate any version of Github.com/ipfs/go bitfield in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1284: Improper Validation of Specified Quantity in Input, where the product receives input that is expected to specify a quantity (such as size or length), but it does not validate or incorrectly validates that the quantity has the required properties. In Github.com/ipfs/go bitfield, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact When feeding untrusted user input into the size parameter of `NewBitfield` and `FromBytes` functions, an attacker can trigger `panic`s. This happen when the `size` is a not a multiple of `8` or is negative. There were already a note in the `NewBitfield` documentation: > ``` > Panics if size is not a multiple of 8. > ```` But it incomplete and missing from `FromBytes`'s documentation. This has been replaced by returning an `(Bitfield, error)` and returning a non nil error if the size is wrong. ### Patches - https://github.com/ipfs/go-bitfield/commit/5e1d256fe043fc4163343ccca83862c69c52e579 ### Workarounds - Ensure `size%8 == 0 && size >= 0` yourself before calling `NewBitfield` or `FromBytes` ### References - https://github.com/ipfs/go-unixfs/security/advisories/GHSA-q264-w97q-q778
